Once the furnace had cooled, Mauri took it outside again and smelted another material.

Mao Rui wants to manufacture firearms, and there are many types of firearms, and the structure is also different, just the general components, the barrel, the bolt, the receiver, the ammunition supply mechanism, the firing mechanism, the aiming mechanism, the holding device six parts.

And this is just the part of the common part of the firearm, in addition, many firearms have their own unique structure. Like automatic firearms, weapons also have automatic mechanisms, machine guns have bipods, tripods, * cheek pads, etc.

And there are many small parts in these structures.

The bolt is composed of a nose, a frame, a shell hook and other parts.

The receiver generally includes the receiver, the receiver cover, the gun joint sleeve, the tailstock, etc.

Ammunition feeding mechanism generally refers to *, drum and machine gun ammunition feeding machine, bullet chain, etc.

Sighting devices include ordinary * quasi-sights, which can also be optical and night-vision sights.

The grip device refers to *, grip, handguard, and handle.

Automatic devices for automatic weapons, including re-entry devices, air conduction devices, and buffer mechanisms.

Each part, each part, has its own different function, naturally can not be refined with the same material.

What Mao Rui has to do is not only to refine many materials into individual parts, but also to combine and try different materials.

Even if Mao Rui first chose to refine a pistol with the fewest parts, the workload was not ordinarily large.

By the time Mao Rui had finished smelting all the materials he thought were suitable for making gun parts, it was half a month later.

Subsequently, Mao Rui smelted the various materials that had removed a large number of impurities, and put them into the smelting furnace to continue calcining, so that the materials began to soften, but did not melt.

Take out an anvil for striking iron from the space bag, and two casting hammers, one large and one small.

The anvil is an anvil bought by the mortal world, and the casting hammer is also a casting hammer bought by the mortal world, the only difference is that after buying, Mao Rui depicted the reinforcement and weight gain formations on the anvil and the casting hammer respectively.

Among the refining experiences left by the Burning Heaven Dao people, there is a method called 'tempering and dequainting', which is to continuously hammer the refining materials through special techniques, so as to remove those impurities that cannot be removed through smelting, so that the purity of the materials reaches a higher level.

Mao Rui felt that this method was very suitable for the firearms and magic weapons he wanted to refine.

However, the current cultivation realm, after years of development, I don't know if it is because it has lost its inheritance or how it has dropped, and the step of forging has been omitted from refining.

There is no need for forging, and the anvil and casting hammer used in forging are naturally not needed.

Mao Rui, who inquired in many ways and didn't get any news of the anvil and the casting hammer, had no choice but to spend a lot of money to buy the anvil and a pair of casting hammers from an old blacksmith shop in the mortal world.

From the melting furnace, take a piece of material with the lowest melting point and have softened and place it on top of the anvil. Then, through the fire control array, the temperature in the furnace is raised to the point where the other refining material can be softened without melting.

Picking up the large casting hammer, spiritual power gushes out and attaches to the casting hammer in some way.

Raise the hammer and aim it at the material.

"Ding"

With a crisp sound, the material, which was originally an ellipsoid, was instantly compressed into an irregular thick cake under the hammer blow. At the same time, due to the tremendous force, the deformed material bounced off the anvil and rolled in the air.

"Ding"

While the material was still tumbling in the air, Mao Rui's second hammer had already fallen.

The material was deformed again, and at the moment of raising the hammer, it jumped from the anvil.

"Ding Ding Ding Ding"

Hammer after hammer kept falling, causing the material to constantly fly in the air, and the crisp sound did not stop at all.

Each time the hammer falls, whether it is the force of the hammer or the time of the hammer, there is no change, the only thing that changes is the shape and volume of the material.

In the continuous falling of the hammer, Mao Rui also understood why the current cultivation realm would omit the forging step when refining the weapon.

He was able to swing the hammer like this, all because he had cultivated the Burning Sky Bone Decision, he was a body cultivator, and his strength was far greater than that of ordinary people. If it was another monk who had not cultivated the body refining method, it would be impossible for him to continue swinging the hammer like this, and his physical strength would be unbearable.

"Ding"

I don't know how many hammers I hit after a long time, and this hammer fell, but Mao Rui found that this hammer had a feeling that it couldn't be beaten.

"Is it not enough temperature?"

Mauri muttered to himself and sent the material into the furnace to soften it again.

After calcining again for a long time, Mao Rui took the material out of the smelting furnace, raised the hammer, and knocked it down.

"Ding"

Mao Rui frowned, the materials had just been taken out of the furnace, but he still had a feeling that he couldn't move.

I tried several times in a row, and the conclusion was the same.

"It's... Spoiled?"

After many attempts, the results were all the same, which reminded Mao Rui of a sentence left by the Burning Heaven Daoist:

"No matter what material, even if it is a piece of mortal iron, after countless tempering, it will not be much worse than a top-level cultivation material. ”

At first, Mao Rui thought it was just a word of encouragement not to give up easily, but now, he found that he had thought too much about this sentence before.

The real meaning is actually as simple as the literal meaning. It is simply to tell people that any material, as long as it has been tempered countless times, can further improve its quality.

"Tempered into steel, that's the same truth. I don't know if this material will continue to change. Looking at the refining material on the anvil table, which was half smaller than the original, Mao Rui muttered to himself.

In order to explore the unknown outcome, Mao Rui raised his hammer again and pulled it down.

"Haha, it's okay now, I can't move at all. I don't know how many times I lifted the hammer again, and after the action of picking it down, Mao Rui said quite embarrassedly.

The original skull-sized material became smaller and smaller under Mao Rui's constant beating. And Mao Rui's hammering is getting more and more difficult, until the volume of the material is only the size of a fingernail, and Mao Rui can no longer help this material.

No matter how high the temperature of the melting furnace is, even if it is high enough to vaporize the material, it will not cause any softening of the deteriorated material.

It can't be softened, and naturally it can't be hammered.

A piece of refining material, because of curiosity, was completely unusable, but Mao Rui did not have the slightest sense of waste and shame, but instead put the material in the space bag.

It's true that there is no way to take this piece of material now, but it doesn't mean that there will be no cultivation in the future.
